DEVICE FOR LESSENING THE NOISE OF FIREARMS.

SPECIFICATION forming part of'Letters Patent 1893. SerialNo. 470234- (Nomodel.) Patented in fiwitzerland December 21, 1892,110. 5,765,

Application filed April 13,

No. 516,236, dated March 13, 1894.

To all whom it may concern:

Be it known that I, JAKOB STAHEL, acitizen Switzerland, residing atWollishofen, near Zurich, in the canton of Zurich and Republic ofSwitzerland,-have inand useful Improvements in Devices for Lessening theNoise of Firearms; and I do hereby declarethe following to be a full,clear,

skilled in the artto which itappertains to make and use the same.

My invention relates to a device for the purpose of reducing ortonations of firearms used in slaughtering catsuppressing the dottle insome cities; although it is equally applicable to firearms employed forother purposes, and for which I have obtained Letters Patent ofSwitzerland, No. 5,755, dated December 21, 1892.

In the accompanying drawings, Figure 1 represents a side elevation of afire arm embodying my invention and fixed to the head of a steer whichis to be butchered; and Fig.

2 represents a longitudinal section-of the '0 same.

' This fire arm is composed of a percussion ev1ce, a barrel and themeans of destroying or greatly lessening the sound of the detonations.The said percussion device consists of a metallic socket a, which isscrewed on the pin or plunger b driven through guide openings in thesaid socket into the cap of cartridge g in the breech end of the barrel,and a spring 0 within the socket for holding the said firing pin awayfrom the and exact description of the invention, such as will enableothers ;said chamber being pin is struck by the operator and driven in.To allow this drivingin, the outer end of the said firing pin normallyprotrudes through the outer end of the said socket. To allow theintroduction of the carca'p until the said tridge into the barrel, thesaid socket is unscrewed and removed at will. The sounddestroyingchamber e has the muzzle of the barrel d screwed into it, and isprovided with an outlet opening in line with the said barrel, throughwhich the bullet is discharged into the animals brain. The said chamber,being of considerably greater diameter and cubical capacity than thesaid barrel allows the expansion ot the gas generated by the burningexplosive and stifles the sound. Straps f f may be employed for holdingthe fire arm to the animals head; but these obviously are not important.

Having thus described my invention, what Patent, is-' In combinationwith the barrel of a fire-arm and discharging devices, a soundsuppressing hamber of greater diameter than the said barrel and attachedto provided with an outlet opening in line with the said barrel for thepassage of the bullet and closed at all other points substantially asset forth.

In testimony whereof I afilx my signature in presence of two witnesses.
